When trails get rocky or the road drops into ruts, a low-hanging axle can hold you back. This heavy-duty Timbren Axle-Less Trailer Suspension eliminates the axle beam completely, giving you more ground clearance while keeping a steady deck height. The long, standard-height spindles fit wide off-road tires (up to 35" x 12.5" x 20") so you can tackle uneven paths without dragging or bottoming out.
Uneven terrain and washboard roads don’t have to mean a beating for your trailer. The built-in AEON rubber jounce and rebound springs absorb shock, reduce bounce, and keep things quiet inside. Each side works independently, so what happens on one wheel doesn’t shake the other. The result is a stable, controlled ride that protects your cargo and makes towing feel calm and solid.
Off-road travel is tough on parts, but this system is ready for it. The suspension arms and hangers are made from robust, heavy-gauge steel designed to handle abuse from heavy loads and rough terrain. A black powder-coat finish keeps rust and corrosion at bay, so you get long service life even in wet or salty conditions.
Keeping your bearings greased is easy thanks to the built-in E-Z Lube design. Just attach your grease gun to the zerk fitting and you’re done—no disassembly needed. If a spindle ever gets damaged, it can be replaced on its own instead of having to swap out the whole suspension. That means less downtime and lower long-term maintenance costs.
This system bolts directly to your trailer’s frame and works with any frame width, making it a clean solution for upgrades or new builds. A 2" x 3" steel crossbeam (not included) or reinforcement bracket can be added through the built-in square holes to keep the frame square and strong. With a 3,500-lb weight capacity and 5-bolt brake flange, it’s ready for single- or tandem-axle setups that need dependable performance on or off the pavement.

They are GREAT! I put them on a small offroad trailer that has followed me all over some really rough roads in remote Oregon, Washington, and Idaho. They have performed flawlessly, helped the trailer tow extremely well, and were the single best upgrade I did to that trailer. Very much looking forward to another summer of exploring! Massive upgrade to the stock axle leaf spring combo, and I have had the opportunity to show it off to alot of fellow overlanders. I cant speak high enough of them. I also purchased a set of airbags for my vehicle which unfortunately have not held up terribly well. I have had to field repair one once already, and neither holds air terribly well. Truth be told they seem very underdesigned for the job they perform. From my super secret high tech pocket internet window.

Ashley, the 4 version doesnt actually give it more travel. Its the same was the standard or the system as far as suspension travel. What the 4 system does it lift the height of the trailer from the ground, depending on what youre doing with the trailer. For an off road trailer I personally would do the 4raise for added ground clearance, just gotta make sure the trailer doesnt get top heavy. The standard system is good for pretty much all uses and the system is for when you need a really low deck height for a lawn mower or go kart for example. I appreciate your review as I am going to be building a small off road campingbug-out trailer to tow behind my lifted FJ cruiser. I havent decided if I am going to go with the standard height or the 4 lift as I am going to be running the same off road tires toyo RT that I have on my FJ on the trailer and I want the trailer to sit around the same height. Did you add brakes to yours? Im planning on either running electric brakes or if available in am going to run surge brakes.

Michael, My trailer was so light even fully loaded that I didnt see the need for brakes and never missed having them.I stand corrected: We did get the 4 lift, but the non-HD instead of the HD because the specs said that it had a bit more travel. and we didnt need the weight capacity. That being said, Im still happy with how this suspension performs. My trailer is on 31s on a stock Cherokee.

Can't wait to hear how the install goes, Christopher! What kind of trailer are you going to install them on?

Its been a year since Ive installed the new axles on my trailer my comments above still hold true. Im very pleased with the ride quality of the system after a year. The trailer tracks true and has hauled many things other than my motorcycle. Even empty it doesnt hop around like the original stock straight axle did. No regrets on the purchase.
